I'm a very great fan of reverbs and have some ones I like to use.
I was watching EMT for a while and, after test it few hours with some of my real mixes, I noticed the it sounds much better than my favorite Plate. I mean it is dense, warm, with nice resolution.
It sounds like a non digital. It sounds real. Good for a lot of things.
It's graphical interface is pretty, simple, fast and easy to use.
EMT now figures my session's Plate's Bus. My favorite reverb now.

Classy, smooth, versatile, elegant and truly professional sounding. So easy to be used in a tasteful way. Brings things to life without the fuss. A terrific and affordable weapon and tribute to the past.

On 80's I mixed a lot of classic albums here in Brasil at Transamérica Studios in São Paulo using the original EMT 240 and EMT 251 reberbs and when i tried the 140 UA Plug ins i came back 25 years and the new experience was amazing!

Jaw dropping. This is the kind of plugin that makes mixing more fun. It adds depth, width, and ambiance. It sounds great on all source material. Reverb plugins usually have really brittle, tinny, a/o false decay tails. I have tried a bunch of other plugins from IK Multimedia, Waves, and a few others. This thing buries them all in terms of sound and usability.

I have been really impressed with most of the UA plugins but this thing is off the scale. I use it on every session now and get amazing results quickly and without fail.

The DAWs I use have their own built in reverbs, so to buy another reverb for a back bedroom studio seemed overkill to me. Then I tried the EMT140 Demo...... I expected it to sound great (and it does!) but the surprise was how EASY it was to get a great sound. In very little time, and with only a few tweaks, you're there, you have a reverb that sounds great in your mix.

I've used many reverb plugins over the years and have always struggled to find one that I really can work with. I find most reverbs to be overly complex and even though I am somebody who uses presets as a basis and adjusts from there, if the options are overwhelming, I get frustrated. This plugin sounds great, but one of the main reasons that I love it is because the controls are few and straight to the point. You can easily adjust the sounds to your taste with the limited amount of knobs. I also want to mention that while most reverbs I always finding myself slowly turning down and down and down until there is a subtle ambience but not a really apparent reverb this might be the first reverb that beckons you to turn it up!

The original EMT plate reverb is a steel monster that needs an isolated vault of its own. With only rudimentary damping and EQ, it is more or less a "set and forget" creature. Instead of a soundproof room, the UA version (really three units in one) just needs a UAD card to run on. While lacking some of the more esoteric settings of other types of reverberators, this classic and classy reverb responds well to a bit of tweaking: for example, fine tune the frequency response to compliment the audio, using both the input filter and the reverb EQ. If you cut the low end or scoop out some mids, you can keep the level and reverb time up without muddying the mix, or you could boost the tops to to add a dreamy air to vocals or acoustic guitar.
Use the modulation control to add movement and harmonic complexity to shimmering sounds.
Try two instances in mono, panned Left and Right: this keeps the centre dry and there is much more sonic room to move.
Or exaggerate the pre-delay to keep the reverb out of the way.
Or send some signal from your delays into the reverb.
Don't be afraid to run an EQ after the reverb.
Or...or...

A great workhorse reverb, and of course you can run several instances at once!
Or use it alongside one of the other great UAD reverbs!

One last hint: make the reverb obvious and do your tweaking. When you are satisfied, drop the reverb level...less is usually more. Automate your levels (and even your tweaks) if you need the reverb to be more obvious at the end of vocal lines etc.

I think this is the best reverb for drums and percussions there is on the software market. It has a nice non-metallic sound, it's kinda hard to explain, very smooth. Way better than dreamverb in my opinion. Also nice when you put it to the Master-Out, EQ it just right and turn it on to 5%, it "glues" the end mix to one piece. And for this price it's better than tc.

I bought a lot of plugs from UA (projpak, fairchild, cambridge, precEQ, preLim, BossFX, LA2A, 1176LN and the Plate 140).
After i mixed a demo (using only the Plate 140 as reverb), i brought the tape to a professional audio-engineer (he had several hits in the german charts).

His comment: "the reverb is not very satisfiying...".

WOW!

I trusted in all the comments and all the evaluations shown up in this area!

I recognized, not to trust in too many people - in the future i will trust my own ears.

Sure - plug-ins give you the possibility to get a certain quality to a low price.

I'll have to be the lone dissenter here. I was disappointed by this plugin, after putting it through its paces. It's just murky and dull sounding. Dreamverb is probably my favorite UAD reverb. But put this up against Sonic Timeworks' gorgeous plate reverbs, or even TC-Helicons, all of which I spent a few days A/B/C'ing with, and it just sounds terrible.

I've been a UAD user for 11 years now and haven't written a review yet. I'm going to remedy this, starting with my favorite plugin: The EMT 140 (or, as it was originally called, "UAD Plate 140").
This is the best reverb I've ever used. It's over a decade old and nothing that's come ou in those intervening years has come close; convolution, room simulations, spot-on emulations of classic digital boxes; they all pale in comparison to the mighty EMT 140. There's other great reverbs out there, but there's something so organic and "real"-sounding about this one. It can be lush, it can be spooky, it excels on vocals, acoustic instruments, synths... anything you can throw at it that needs a big, warm, beautiful reverb. Classic.
